pip install psutil gpiozero flask
创建app.py文件：

app = Flask(__name__)
def get_system_info():
cpu = psutil.cpu_percent(interval=1)
mem = psutil.virtual_memory()

return {

'mem_used': mem.used / (1024 ** 3),
'mem_percent': mem.percent,

def dashboard():
return render_template('dashboard.html', data=get_system_info())
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000)
创建templates/dashboard.html:

python app.py
在浏览器中访问: http://<你的树莓派IP>:5000
sudo nano /etc/nginx/sites-available/monitoring
添加以下内容:
server {
listen 80;
server_name your_domain_or_ip;
location / {
proxy_pass http://127.0.0.1:5000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
sudo ln -s /etc/nginx/sites-available/monitoring /etc/nginx/sites-enabled
sudo nginx -t
sudo systemctl restart nginx
创建systemd服务:
sudo nano /etc/systemd/system/monitoring.service
添加:
[Unit]
Description=Raspberry Pi Monitoring Service
After=network.target
[Service]
User=pi
WorkingDirectory=/home/pi/monitoring
ExecStart=/home/pi/monitoring/venv/bin/python /home/pi/monitoring/app.py
Restart=always
[Install]
WantedBy=multi-user.target
启用服务:
sudo systemctl daemon-reload
sudo systemctl enable monitoring.service
sudo systemctl start monitoring.service
现在你有了一个功能完善的树莓派监控仪表板，每5秒自动刷新显示关键系统指标！
